Ophcrack is a Windows password cracker based on a time-memory trade-off using rainbow tables. This is a new variant of Hellman's original trade-off, with better performance. It recovers 99.9% of alphanumeric passwords in seconds. Features: - Runs on Windows, GNU/Linux, FreeBSD, Mac OS X, etc. - Cracks LM and NTLM hashes - Free tables available for alphanumeric LM hashes - Brute-force module for simple passwords - Audit mode and CSV export - Real-time graphs to analyze passwords (optional) - Loads hashes from local and remote SAM - Loads hashes from encrypted SAM recovered from a Windows partition, Vista included - Supports soon to be released XP flash and Vista eight XL tables

L0phtCrack 1.5 is a tool for turning Microsoft LANMAN and NT password hashes back into the original clear text passwords. The program does this using dictionary cracking and also brute force. L0phtCrack returns not just the LANMAN password but the NT password up to 14 characters in length. L0phtCrack includes the ability to dictionary attack or brute force the network NT server challenge that is used to prevent the OWF (one-way format) from going across the wire in its plain-text format. Sample network sniffed challenges are in files sniff.txt and sniff2.txt. This means you can obtain NT passwords without administrator privileges when you have network access between the client and the server.

After examining Tripwire and deciding that it was *way* overkill for my own purposes... ...L5 simply walks down Unix or DOS filesystems, sort of like "ls -R" or "find" would, generating listings of anything it finds there. It tells you everything it can about a file's status, and adds on an MD5 hash of it. Its output is rather "numeric", but it is a very simple format and is designed to be post-treated by scripts that call L5... ...Unlike Tripwire itself, this is NOT a complete toolkit -- one is expected to use it as a small, reliable part of a larger system... _H* Andrew McNaughton <andrew@scoop.co.nz>

Lasso is a free software C library aiming to implement the Liberty Alliance standards; it defines processes for federated identities, single sign-on and related protocols. Lasso is built on top of libxml2, XMLSec and OpenSSL and is licensed under the GNU General Public License (with an OpenSSL exception). Lasso first focused on implementing the Liberty Alliance ID-FF 1.2 protocols. It now supports a good part of ID-WSF, and SAML 2.0 support has also been completed.

Crypt::LE provides the functionality necessary to use Let's Encrypt API and generate free SSL certificates for your domains. It can also be used to generate RSA keys and Certificate Signing Requests or to revoke previously issued certificates. Crypt::LE is shipped with a self-sufficient client for obtaining SSL certificates - le.pl. The client supports 'http' and 'dns' domain verification out of the box.

PKCS #11 module for Belgian government-issued electronic identity cards.

The Blowfish Library Blowfish is a block cipher that operates on 64bit (8 byte) quantities. It uses variable size key, but 128bit (16 byte) key would normally be considered good. It can be used in all the modes that DES can be used. This library implements the ecb, cbc, cfb64, ofb64 modes. Blowfish is quite a bit faster that DES, and much faster than IDEA or RC2. It is one of the faster block ciphers. -- Jim Geovedi jim@corebsd.or.id
